采用混沌函数的图像加密算法

提出一种新的图像加密算法,采用混沌函数与"按位异或"操作相结合的方法对图像加密。该算法能够产生一个较大的密钥空间足以抵御外力攻击,能够安全地对图像加密,并具有很强的对密钥和原图像的敏感性,密文图像具有高度的非相关性,而密文具有良好的随机性。实验结果验证了算法的有效性,可以满足图像安全加密的要求。

Image Encryption Based on a Chaos Function

A novel efficient algorithm is proposed to encrypt images using the combine chaos function and XOR operator.This algorithm can produce a large key space to resist attacks,and encrypt securely images.The proposed algorithm exhibits extreme sensitivity to key and original image,and the cipher image has high non-correlation among pixels,and the ciphers have a high level of randomness.The experimental results show that the algorithm is efficient and secure enough to be used for the image encryption.
